Title: Piezoelectric actuator
Inventor: TSUTSUI OSAMU
IPC: H02N2/00
Filed: 1988-10-08
Abstract: PURPOSE:To enable the accurate operation of a piezoelectric actuator without decreasing the clamping force to a plunger by a method wherein, when the operating speed of the piezoelectric actuator is decreased, only the applied voltage to a piezoelectric element for stroke use is changed, and the applied voltage to a piezoelectric element for clamp use is kept constant. CONSTITUTION:In accordance with an input from a valve opening and shutting switch, a control signal is output to an actuator A of a diaphragm valve V1 from a control unit C, and drives each piezoelectric element to make said valve V1 execute an open and shut operation. At the time of operation speed control of the piezoelectric actuator, only the applied voltage to a piezoelectric element for stroke use is changed, and the applied voltage to a piezoelectric element for clamp use is kept constant. As a result, also when the operation speed is decreased, only the applied voltage to the element for stroke use is changed, and the applied voltage to the element for clamp use can be kept constant. Thereby, the clamping force to a plunger is not decreased, and the generation of plunger slip can be prevented, so that the accurate operation of piezoelectric actuator is enabled.

Title: Paper delivery device
Inventor: HASEGAWA KAIICHI
IPC: B65H5/00
Filed: 1984-11-30
Abstract: PURPOSE:To ensure a distance between a preceding and a following paper and to eliminate a fear of counting error occurring, by a method wherein a delivery drum is rotated following rotation of the rotary driving part of an inertia drum, and constitution of a rotary cam, being capable of running and rotating at a given angle, is employed. CONSTITUTION:With a motor 5 driven, a delivery roller 4 is rotated, a rotation transmitting member 22 is rotated, and this causes a delivery roller 7 to rotate through a rotary cam 28. An inertial drum 15 is rotated at a speed higher than that of a deliver drum 7 through a feed-out roller 17. Since a lead angle at a given angle is allowable to the delivery drum 7 by means of the rotary cam 28, the drums 7 and 15 are temporarily rotated at the same speed as each other to deliver a note 2. Right after the rear end of the note 2 is moved away from a nip formed by the drum 7 and a pressurizing member 11, transmission to the cam 28 by means of an engaging pin 27 is shut off, and rotation of the drum 7 is temporarily stopped. The pin 27 is brought into contact with a cam groove 29, and the cam is rotated again. This enables reliable formation of a distance between the notes, and performs counting without error.

Title: Motor and elevator
Inventor: NIHEI HIDEKI
IPC: H02K1/14
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To provide with simple alignment between a slit and a slot a motor and elevator for which eddy current effect is reduced, without adversely affecting motor property. SOLUTION: Eddy current due to the magnetic flux having leaked out from the width direction of a tooth tip can be reduced, and the core loss can be reduced by that amount, by forming a second slit 32 in a direction orthogonal to a first slit 31, at a section opposite to the tooth tip face of a thin plate 3, forming the second slit 32 longer than the width of the tooth tip face (the length in the circumferential direction). Especially, the drop in the magnetic flux due to the slit 32 can be lessened by forming the second slit in the position of a stack face 15 of silicon steel plates, and the motor output can be raised, compared to the case of providing it in an arbitrary position.

CONSTITUTION:When a user places a container onto a weight detecting stage 10 in order to put in hot water, a weight sensor part 14 detects a variation of weight, and an electric circuit part 16 compares whether said weight coincides with weight of the container stored already in its memory or not. When they coincide with each other, the quantity of hot water which is put into its container in the previous time, stored in the memory is read out, the hot water pouring quantity is always lighted in an electric display means, and by driving a motor-driven pump 17, hot water pouring is started. After hot water pouring is started, whether a value obtained by subtracting the container weight before hot water pouring, and force received by dropping of hot water, from weight detected from the weight sensor part 14 is equal to the prescribed hot water pouring quantity or not is decided successively and at time point when they become equal to each other, the motor-driven pump 17 is stopped. In the case poured hot water is not put into the container but split, it is detected by a hot water spill detecting part 11, and hot water pouring is suspended immediately.

Title: Bit synchronizing device
Inventor: SEKI YOSHINORI
IPC: H04L25/02
Filed: 1991-10-03
Abstract: PURPOSE:To obtain the bit synchronizing device of a simple constitution, which can extract a synchronization timing from a bit synchronizing signal of several bits. CONSTITUTION:An edge detecting routine 2 counts the number of sampling pulses to each code variation point of a bit synchronizing signal contained in a receiving signal S1. A jitter measuring routine 3 derives a jitter of every bit by calculating a difference between the number of sampling pulses to each code variation point which is counted, and the number of sampling pulses to each code variation point to be counted in the case there is no jitter. The jitter measuring routine 3 calculates an average value of a jitter of a 5-bit portion. A synchronization setting routine 4 corrects a jitter component with the average value of this jitter, and sets a phase so that a timing of a sampling pulse supplied to a data store part 5 becomes the center of each bit of receiving data contained in the signal S1. The data store part 5 inputs the receiving data at the timing of the sampling pulse to which the phase is set in such a way, and stores it.

Title: Rotary tiller
Inventor: FUJIMOTO SATOSHI
IPC: A01B33/08
Filed: 1987-10-12
Abstract: PURPOSE:To simplify operations required for a tine shaft positioned inside the turning movement of an automotive frame and smoothly perform the turning operation of the frame at the turning movement of the frame in a puddling work, by providing in a transmission case a clutch which stops the driving of the tine axis positioned inside the turning movement of the automotive frame while interlocking with the turning movement. CONSTITUTION:A clutch C stopping the driving of a tine shaft (6L or 6R) positioned inside the turning movement of an automotive frame while interlocking with the turning movement is provided in a transmission case 4. When a rotary tiller is placed in a field and its automotive frame is turned, a resistant plate 11 is swung inside the turning movement due to the resistance of earth and a shift fork 13 allows a driven sprocket 10 to shift outside the turning movement. The intermeshing of the driven sprocket 10 with the tine axis (6L or 6R) positioned inside the turning movement is disconnected and the transmission of power is cut, thereby stopping the driving of the tine axis.
